Urgent Hard Drive/MoBo/ Something Problem!

About 1 to 2 months ago i bought a new harddrive (http://www.westerndigital.com/en/products/Products.asp?DriveID=133)
and i installed it with everything working successful. last week I noticed a huge bog down on my speed while doing everything from boot-up, playing games, to just browsing the web.... Finally last night i got the dreaded BLUE SCREEN!, This one was a "Machine Exception Error" blah blah "windows has shut down to prevent damaging hardware, if this is ur first time please go into windows bios and turn of Cache Shadowing, something something," gives me a big terminal error at the bottom (00000x01) or something and then it reboots, this all happens in a matter of 5 seconds so i dont really have enough time to read it all.




Specs:
Operating System Microsoft Windows XP Professional
CPU Type DualCore AMD Athlon 64 X2, 2000 MHz (10 x 200) 3800+
Motherboard Name DFI nF4 Series
Motherboard Chipset nVIDIA nForce4, AMD Hammer
System Memory 2048 MB (PC3200 DDR SDRAM)
Video Adapter NVIDIA GeForce 7800 GT (256 MB)
(Old HD Set as Slave)Disk Drive Maxtor 6Y120P0 (120 GB, 7200 RPM, Ultra-ATA/133)
(New HD)WDC 250 16mbcache SATA

Edit: I am in the debugging process jumping between my friends and such, and I have installed windows on both of my HD's and noticed that they seem to be bootable on my friends computer but not on mine, so i am thinking about it, and maybe it is NOT my HD, but I have no idea what it could be, or who I should call for support? my mobo disb, or my HD disb(s), any help is great



Thanks,

Update---

Well i literally took my pc apart and tested my HD's at my friends, ran Memtest86 for my memory, ran HD scans.... so far my memory isn't bad, my HD's work at my friends house fine, I looked for blow capacitors, nothing there (or buldging ones) finally I smelled my processor chip/heat sink and it smelled like burning... I took it out and the chip was literally melted onto my heatsink (i put on the paste/silicon base whatever that stuff is) and I'm pretty sure its just busted. Any ideas? I have a 3 year warrenty on it, but does that mean my Motherboard is crap to since i took out the chip or just replace my processor? Thanks
